Honeywell C7015A Infrare d Flame Detector The C7015A Flame Detector includes a lead sulfide photocell that is sensitive to the infrared radiation emitted by the combustion offuels such as natural gas, oil, and coal. n q w n n Particularily suitable for combination or dual-fuel radiation is compatible with a wide range of flame applications.
C7015A SPECIFICATIONS l ORDERING INFORMATION Specifications SUPER TWELINE MODELS SUPER TRADELINE models offer features not available on TRADELINE or standard models, and are designed to replace a wide range of Honeywell and competitive controls.
WIRING CONNECTIONS: Nominal 30, 48 , or 96 in. [0.76, 1.22, or 2.44 ml leadwire+hvoNo. 18 AWG,flexible-tinnedconduc- tom; rated for 194°F [90” C]; twistedpair-onebrown and one white. Underwriters Laboratories Inc. listed: File No. MP268. Canadian Standards Association certified: Master file LR-95329-1.
C7015A OPERATION l INSTALLATION Operation OPERATION OF INFRARED DETECTORS Infrared detectors can be used with gas, oil, coal, or dual- fuel flames. Since more than 90% of the total flame radiation is infrared, these detectors receive ample radiation and can detect weak fkunes as well as flames of higher intensity.
C7015A INSTALLATION is available to facilitate flame sighting after the C7015A is pipe diameter is reduced, the effect is the same as adding an mounted. orifice plate to the pipe as discussed below. FIELD OF VIEW A lead sulfide photocell, like other photocells, views an area rather than a point.
C7015A INSTALLATION INSTALLING AN ORIFICE PLATE AnorificeplatewithahexagonalorificediameterofO.125 in. [3.2 mm] is available for the C7915A Infrared Flame Detector. The orifice can be mounted i n front of the cell in the seal-off adapter or in a standard 314 in.
C7015A INSTALLATION RESPONSE TO HOT REFRACTORY Although the infrared amplifier will not respond to steady radiation, as produced by hot refractory, be careful to protect the infrared detector from hot refractory radiation because of two possible conditions , shimmer and raa’iation saturation.
C7015A INSTALLATION CLEARANCE Make sure there will be enough mom to easily mount the sight pipe, flame detector, and all required accessories, and to remove th e flame detecto r for troubleshooting and servicing.
